Tweaking RuleSetDialog to Resize

I've started working with Windows Workflow Rulesets to apply dynamically apply business rules to some internal processes. This involves using External RuleSet Toolset from Microsoft samples (some more on that in a later post)

One of the biggest peeves about the RuleSetDialog is its inability to resize. Viewing a complex rule in a three line window is very uncomfortable. It is, however, pretty easy to tweak the dialog and make it a lot more user friendly.

External RuleSet editor comes in source code. Open the code using Visual Studio, open the code for the RuleSetEditor form and find the editButton_Click event. What you'll may notice is that the RuleSetDialog class used derives from Dialog. Add a new function that will adjust the dialog to make it resizable.

private void TweakRuleSetDialogToResizable(RuleSetDialog ruleSetDialog)
        {
            ruleSetDialog.FormBorderStyle = FormBorderStyle.Sizable;
            ruleSetDialog.HelpButton = false;
            ruleSetDialog.MaximizeBox = true;
            ruleSetDialog.Controls["okCancelTableLayoutPanel"].Anchor = AnchorStyles.Right | AnchorStyles.Bottom;
            ruleSetDialog.Controls["rulesGroupBox"].Anchor = AnchorStyles.Left | AnchorStyles.Top | AnchorStyles.Right;
            ruleSetDialog.Controls["ruleGroupBox"].Anchor = AnchorStyles.Left | AnchorStyles.Top | AnchorStyles.Right | AnchorStyles.Bottom;
            ruleSetDialog.Controls["ruleGroupBox"].Controls["thenTextBox"].Anchor = AnchorStyles.Left |
                                                                                    AnchorStyles.Top |
                                                                                    AnchorStyles.Right | AnchorStyles.Bottom;
            ruleSetDialog.Controls["ruleGroupBox"].Controls["elseLabel"].Anchor = AnchorStyles.Left | AnchorStyles.Bottom;
            ruleSetDialog.Controls["ruleGroupBox"].Controls["elseTextBox"].Anchor = AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Bottom;
            ruleSetDialog.Controls["ruleGroupBox"].Controls["conditionTextBox"].Anchor = AnchorStyles.Left |
                                                                                         AnchorStyles.Top |
                                                                                         AnchorStyles.Right;

            ruleSetDialog.Controls["rulesGroupBox"].Controls["panel1"].Anchor = AnchorStyles.Left | AnchorStyles.Top | AnchorStyles.Right;
            ruleSetDialog.Controls["rulesGroupBox"].Controls["panel1"].Controls["chainingBehaviourComboBox"].Anchor = AnchorStyles.Top | AnchorStyles.Right;
            ruleSetDialog.Controls["rulesGroupBox"].Controls["panel1"].Controls["chainingLabel"].Anchor = AnchorStyles.Top | AnchorStyles.Right;
        }

Then call the function passing the RuleSetDialog before it is display from the editButton_Click event.

                    RuleSetDialog ruleSetDialog = new RuleSetDialog(selectedRuleSetData.Activity, null, selectedRuleSetData.RuleSet);

                    //Tweak the RuleSetDialog
                    TweakRuleSetDialogToResizable(ruleSetDialog);

                    DialogResult result = ruleSetDialog.ShowDialog();
